Don't want to hate on your cable management but if you run the GPU power cables into the back of the system and out of the lower black rubber grommet you can get a cleaner look with the cables running straight out and then bending up and down to connect to the GPU's. (you can look at picture 2 from my build for reference on what i am describing) that is really just an idea. other than that really sweet build. Oh, thank you for the well though input on my build as well man.
